ASP.NET MVC routes

Question

I need help with this route map

routes.MapRoute("Blog_Archive", 
                "Blog/Archive/{year}/{month}/{day}",
                new { 
                      controller = "Blog",
                      action = "archive",
                      year = "",
                      month = "",
                      day = "",
                      page = 0
                    });

When I call http://localhost:5060/blog/Archive/2008/11, it picks up the year and month and sends it to the controller. But when I try http://localhost:5060/blog/Archive/2008
it sends it to the controller but the year parameter is null and so are all the other parameters.

Answer 1

Do you have any other Route for Blog/Archive/{something}?

Use the Routing Debugger to see which route actually gets hit, most likely it's not hitting that route.

Answer 2

i can't get the Routing Debugger to work it gives this error

details about exception: System.NullReferenceException: Object reference not set to an instance of an object.

StackTrace:

public static void RegisterRoutes(RouteCollection routes)
 {

  routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
  routes.IgnoreRoute("favicon.ico");

  routes.MapRoute(
   "Blog",
   "Blog/{action}/{id}",
   new
   {
    controller = "Blog",
    action = "show",
    id = ""
   });

  routes.MapRoute("Blog_Archive", "Blog/Archive/{year}/{month}/{day}", 
   new { 
    controller = "Blog",
    action = "archive",
    year = "",
    month = "",
    day = "",
    page =0
   });

  routes.MapRoute(
   "Xfire",                                     
   "Xfire/{action}/{id}",                       
   new
   {
    controller = "Xfire",
    action = "show",
    id = ""
   });

  routes.MapRoute(
   "Photos",                                        
   "Photos/{action}/{id}",                          
   new
   {
    controller = "Photos",
    action = "show",
    id = ""
   });

  routes.MapRoute("About","About",
      new
      {
       controller = "home",
       action = "about"
      });

  routes.MapRoute("Default", "{controller}/{action}/{id}",
      new
      {
          controller = "Blog",
          action = "show",
          id = ""
      });

  routes.MapRoute("Error", "{*url}", new
  {
   controller = "Home",
   action = "Http404"
  ,
  });

 }

found the error

routes.MapRoute("Blog","Blog/{action}/{id}",
                  new {
      controller = "Blog",
                        action = "show",
                        id = ""
                      });

is before

routes.MapRoute("Blog_Archive", "Blog/Archive/{year}/{month}/{day}", 
                  new { 
                        controller = "Blog",
                        action = "archive",
                        year = "",
                        month = "",
                        day = "",
                        page =0
                      });

Answer 4

Subnus, I noticed in your code that you have routes.IgnoreRoute("favicon.ico"); I don't think this is required with MVC 1.0 right because the period is no longer ignored correct?
